  2. Balance point temperature - Wikipedia

    en.wikipedia.org/wiki/Balance_point_temperature

    The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.

  3. Center of mass - Wikipedia

    en.wikipedia.org/wiki/Center_of_mass

    This toy uses the principles of center of mass to keep balance when sitting on a finger. In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero.

    The move compromised the aircraft's balance to the point that control of the aircraft was lost. [6] In July 2013, a de Havilland Canada DHC-3 Otter departed Soldotna, Alaska, stalled after rotation and crashed 2,300 ft (700 m) away from its brake-release point as it was overloaded by 418 lb (190 kg) and its CG was well aft of the rear limit ...

  5. Balancing of rotating masses - Wikipedia

    en.wikipedia.org/wiki/Balancing_of_rotating_masses

    A less tedious means of achieving dynamic balance requires just four measurements. 1) initial imbalance reading 2) an imbalance reading with a test mass attached on a reference point 3) The test mass moved to 120 degrees ahead and the imbalance again noted. 4) The test mass finally moved to 120 degrees behind the reference point.

  6. Heating degree day - Wikipedia

    en.wikipedia.org/wiki/Heating_degree_day

    Heating degree days are defined relative to a base temperature—the outside temperature above which a building needs no heating. Base temperatures may be defined for a particular building as a function of the temperature that the building is heated to, or it may be defined for a country or region for example.

  7. Barycenter (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Barycenter_(astronomy)

    In astronomy, the barycenter (or barycentre; from Ancient Greek βαρύς (barús) 'heavy' and κέντρον (kéntron) 'center') [1] is the center of mass of two or more bodies that orbit one another and is the point about which the bodies orbit. A barycenter is a dynamical point, not a physical object.

    Then, nutrition information was pulled from the Department of Agriculture FoodData Central and Nutritionix to calculate the number of calories, protein, fiber, sugar, and fat (saturated and ...

  9. Lagrange point - Wikipedia

    en.wikipedia.org/wiki/Lagrange_point

    The reason these points are in balance is that at L 4 and L 5 the distances to the two masses are equal. Accordingly, the gravitational forces from the two massive bodies are in the same ratio as the masses of the two bodies, and so the resultant force acts through the barycenter of the system.
